Choosing the Right Greenhouse Plastic: Thickness, Light Transmission, and Film Types
Selecting the appropriate greenhouse plastic is crucial for ensuring optimal plant growth, energy efficiency, and structural durability. Two primary considerations are:
- What’s the best thickness for greenhouse plastic?
- Does greenhouse plastic sheeting block too much sunlight?
Understanding these factors, along with the different types of polyethylene films available, including innovative options like SolaWrap, will help you make an informed decision for your greenhouse needs.
What’s the Best Thickness for Greenhouse Plastic?
Understanding Greenhouse Plastic Thickness
Greenhouse plastic thickness is typically measured in mils (1 mil = 0.001 inches). The thickness you choose affects the durability, insulation, and light transmission of your greenhouse covering.

Does Greenhouse Plastic Sheeting Block Too Much Sunlight?
Balancing Light Transmission and Plant Health
Adequate light transmission is vital for photosynthesis and healthy plant development. However, the quality and intensity of light must be balanced to prevent issues like overheating or uneven growth.
Light Transmission of Different Greenhouse Films
| Plastic Type |
Light Transmission (%) |
Features |
| Clear Polyethylene Film |
85-90% |
Maximizes light; suitable for seedlings and winter growth. |
| White/Diffused Polyethylene Film |
50-70% |
Diffuses light to reduce shadows; ideal for uniform plant development. |
| Infrared (IR) Treated Film |
80-85% |
Retains heat; beneficial in colder climates. |
| SolaWrap Greenhouse Film |
83% |
Provides high transparency with up to 83% light diffusion, ensuring even light distribution
|
Key Insight: SolaWrap not only offers high light transmission but also diffuses light effectively, preventing hotspots and promoting uniform plant growth.
Types of Polyethylene Films for Greenhouses
1. UV-Resistant Polyethylene Film
- Thickness: Typically 6 mil.
- Benefits: Protects against UV degradation, extending the film's lifespan.
- Ideal For: Standard greenhouse applications requiring a balance between cost and durability.
2. Anti-Drip (Condensation-Control) Film
- Thickness: Usually 6-8 mil.
- Benefits: Reduces condensation buildup, minimizing the risk of plant diseases.
- Ideal For: Humid environments where condensation is a concern.
3. Infrared (IR) Treated Film
- Thickness: Around 6 mil.
- Benefits: Enhances heat retention, maintaining warmer temperatures during cooler periods.
- Ideal For: Greenhouses in regions with significant temperature fluctuations.
4. SolaWrap Greenhouse Film
- Thickness: Approximately 334 mils.
- Benefits:
- Exceptional Durability: Withstands heavy snow loads up to 120 lbs/sq ft and wind speeds up to 100 mph
.
- Superior Insulation: The bubble design provides an R-value of 1.7, retaining up to 95% of heat radiation.
- High Light Diffusion: Ensures even light distribution, reducing the risk of plant burn and promoting uniform growth.
- Ideal For: Long-term installations in areas prone to extreme weather, and for growers seeking to maximize energy efficiency and plant health.
Final Thoughts: Selecting the Optimal Greenhouse Plastic
When choosing the right greenhouse plastic, consider the following:
- Durability Needs: For short-term projects, thinner films like 3-4 mil polyethylene may suffice. For long-term use, especially in harsh climates, options like SolaWrap offer superior durability and longevity.
- Light Transmission Requirements: Assess the light needs of your plants. High light transmission is essential for some species, while others benefit from diffused light to prevent scorching.
- Budget Considerations: While initial costs are a factor, investing in a durable, long-lasting film like SolaWrap can result in cost savings over time due to reduced replacement frequency and energy efficiency.
By evaluating these factors, you can select a greenhouse covering that best supports your horticultural goals.
